To @ZZ whom it mayconcern.A

`Be it known that I, THOMAs MODONALD, a citizen of the-United States,and a resident of Youngstown, in the county of Mahoning and State ofOhio, have invented certain new and useful Improvements inCinder-Ladles, fully described and represented in the followingspecification and the accompanying drawings.

This invention relates to the cast-iron lining, hereinafter specified asthe 'thimble, with which all modern cinder car ladles are equipped.

The object of my invention isto obviate a defect which is associatedwith the use of all previously-known thimbles havingremovable bottoms.It has been customary to secure the removable bottoms of these thimblesby removable bottom C.

means of bolts tothe ladle proper, the result being that the presence ofiron in the cinder soon cuts away the tops of these bolts,v which thenact as conductors, leading -the iron directly to the steel ladle anddestroying the same.

My invention consists in securing the vre'- movable bottoms withoutmaking any connecl tions to the ladle.

The accompanying drawings show the sim-V4 plest method of accomplishingmy aims.

Figure l is a vertical cross-section through a cinder-ladle equippedwith a cast-iron thimble having a removable bottom, and Fig. 2 isy a topplan view of the same embodying my,

invention.

Referring to Fig. 1, A is the outer shell or ladle proper. B Visgthecast-iron lining or thimble, the latter being provided with the positionby having its flange D secured to flange E of ladle by means of bolts F.The" flange G serves to support the ladle in a bail. (Not shown.)Recesses H are cut into the circumference ,of opening in bottom ofthimble B. The removable bottom (lis-,supportedA on the bottom ofthimble B by means of ange K. `Lugs N on the under side of C coincide'lThe thimble isheld in tom o will be secuelyfastened to the thimble bymeans of the lugs Nl and iiange K straddling the edge of opening in thebottom of thimble B.

R is a layer of refractory material filling the space between the ladleand the bottom C to be understood as asserting, broadly, my i claimsto'originality in securing the removable bottoms ofthimbles forcinder-ladlesV Awithout Aattaching same to the ladle proper,

and it is obvious that this invention maybe embodied in widely-varyingforms.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-,

1. A cinder-ladle or-the like consisting of an outer ladle, an innerthimble so supported that its bottom isn'otin contact with the ladle,the space between bottoms of ladle vand thimble packed with a refractorymaterial, a removable bottom for the thimble, and having means riot inVcontact with thev outer ladle for securing the removable bottomto thethimble, substantially asdescribed. 2. A cinder-ladle or the-likeconsisting of an oute rladle, an inner thimble so supported that its-bottom is not in contact with the ladle, thel space between bottomsVof, ladle and thimble packed with a refractory material, a removablebottom for the thimble, this removable bottom having lugs onthe underside fitting into recesses in the bottom-of the thimble, said lugstogether with the upper part ofthe bottom forming means .for securingthe removable bottom to the thimble, substantially as described.

3. A cinder-ladle or the like consistingof an outer ladle, an innerthimble so supported that its vbottom is not in contact with the-ladle,the

space between bottoms of ladle and. thimble packed with a refractorymaterial, a removable bottom for the thimble, this removable bottomhaving lugs on the under side fitting into recesses in the bottom of thethimble, said lugsv together with the upper part of the bot-` IOO tomforming means for securing the removable bottom to the thimble byrotating the bottom to the right or left after lugs have passed throughabove mentioned recesses, substantially as described.

4. A cinder-ladle or the like consisting of an outer ladle, an innerthimble so supported that its 'bottom is not in contact with the ladle,the space between the bottoms of the ladle and thimble packed with arefractory material, a removable bottom for the thimble, this removablebottom having lugs fitting into recesses in the bottom of the thimble`said lugs together with the upper part of the bottom forming means forsecuring the removable bottom to the thimble by rotating said bottom tothe right or left after the lugs have passed through above-mentionedrecesses; and spanner-holes in the upper side of the removable bottomadapted to receive a Spanner by which to rotate said bottom;substantially as dcscribed.

5. A cinder-ladle or the like comprising an inner and outer vessel, aremovable bottom in the inner vessel and means not in contact with theouter vessel Jfor securing` said removable bottom to the inner vessel.

6. Acinder-ladle or the like comprising an inner and outer vessel, theinner vessel being of cast-iron and having a removable cast-iron bottom;means on said inner vessel and means on said bottom together forming thelocking` means to hold said bottom in place.

In testimony whereoi1 I have signed this specication in the presence olEtwo subscribing Witnesses.
